Biobehavioral research on coronary heart disease: where is the person?

This study examined the thesis that patients with coronary heart disease (CHD) comprise discrete personality subtypes and that identification of these subtypes may benefit biobehavioral research on CHD. Measures of Negative Affectivity, Social Inhibition, and Self-Deception were used to generate a personality taxonomy through cluster analysis in a sample of 405 men with CHD. This empirical taxonomy served as a basis for the development of a conceptual model which delineates hardy, distressed, inhibited, and repressive subtypes. Coronary proneness may differ across these subtypes to the extent that potential behavioral correlates of CHD were associated with subtype membership. Distressed individuals (characterized by elevated levels of Type A behavior, anger, hostility, and life stress) and inhibited individuals (characterized by the nonexpression of anger) may be particularly coronary prone. It is concluded that research should focus on the interaction of global traits that may define subtypes of patients with CHD.
